For Magnetic Resonance Imaging (MRI) applications, it can be important to collect auxiliary physiological data in conjunction with the Nuclear Magnetic Resonance (NMR) image data. This auxiliary data includes physiological signals such as: Electrocardiogram (ECG), Electromyogram (EMG), Electroculogram (EOG), Electrogastrogram (EGG), Temperature, Respiration, Eccrine Activity (EDA, EDR, SCL, SCR or GSR), Blood Volume Pulse (PPG), Hand Grip Strength (Dynamometry), Finger Twitch, and a variety of pressure based signals.
This application note addresses some of the practical concerns associated with collecting physiological data during the MRI scanning process. Practical concerns relate to the ability to collect such data while maintaining:
A safe environment for the subject.
High quality NMR image data.
IMPORTANT!See Safety Guidelinesfor recording biopotential measurements in the MRI environment.
